27333b0ef2 jifmux: Do not limit the size of the image on 16bits
Use guint instead of guint16 to represent the size of the encoded image,
this would make some recombined images lose most of their data and
show like a big black image with a small line of content on top.

Also adds a minor log message.

d49acb5588 jifmux: Detect EOI correctly
EOI are not always at the last 4 bytes. We need to search
the last 5 bytes to find the 0xFFD9 sequence as jpegenc seems
to round the buffer size to the next 4 multiple.

407f615887 jifmux: Avoid recombining RGB jpegs
JFIF only allows YUV as colorspace, when we receive an RGB jpeg,
we should just push it forward without adding the JFIF marker.

Fixes #627413

20a8666388 Revert "jifmux: Merge xmp and tagsetter tags."
This reverts commit 4e5c412234.

jifmux shouldn't be able to handle jif and shouldn't expect
any xmp on its data. So, no need to handle them.

4e5c412234 jifmux: Merge xmp and tagsetter tags.
When the current file already has tags, they shouldn't be ignored,
parse them and merge with the tagsetter ones.

0d637e4f09 jifmux: Avoid adding 2 xmp packets
jifmux was only appending a new xmp packet to the stream,
it should replace if there is already one.

6c6ea0b79b jpegformat: add a basic jifmuxer
The new element can chop and reassemble the markers. I implements the tagsetter
and for now can serialize some tags to jpeg comments.
